Another attempt at Windows support (less ifdefs)

[adsr]

See #58 for the first attempt.

I tried compiling under msys/ucrt64, but got a compiler error.

Any ideas how to fix this?

Hi @sewbacca thank you for trying this out. I'm not near my Windows machine but I pushed 94b5082 which is completely untested but may fix your issue. I'll try it on my setup soon.

[sewbacca]

Thanks for your quick response! It does compile now, but I don't have an example to test it against, because I just stumbled accross this library and want to check it out :D

[sewbacca]

I'm not sure if I did something wrong, but I believe tb_peek returns an invalid error code:

Unknown error 0 on Windows

#define TB_IMPL
#include <termbox2.h>

int main()
{
        tb_init();
        struct tb_event event = {};
        int err = TB_OK;
        while(event.key != TB_KEY_CTRL_C) {
                err = tb_peek_event(&event, 100);
                if(err != TB_OK && err != TB_ERR_NO_EVENT && !(err == TB_ERR_POLL && tb_last_errno() == EINTR))
                        break;
        }
        tb_shutdown();

        if (err != TB_OK)
                printf("%s\n", tb_strerror(err));
}

@sewbacca Hm, that's strange. TB_OK should equal zero, so I'm not sure what's happening there. I'll have a closer look next time I'm on a Windows machine.
